[SOLVED] 1 Array + 1 Function + 1 Calculation = 1 Big Headache

[tcollie]

Okay, I've created a function to calculate the max amount that can be purchased for a market system.  It looks like this:

 

function market_max($cash)
  {
  include('includes/_config.php');
  $max['product_01'] = $cash/$config['product_01'];
  return $max;
  }

 

And my includes/_config.php code:

$config['product_01'] = 1;

 

And my script:

$cash = 1000;
market_max($cash);
print_r($max);

This doesn't output anything.  But if I just code it outside the function like this, it works:

 

include('includes/_config.php');
$cash = 1000;
$max['product_01'] = $cash/$config['product_01'];
print_r($max);

Output:
Array ( [product_01] => 1000 )

 

Where am I going wrong???

$max = market_max($cash);

you need either

 

$cash = 1000;
print_r(market_max($cash));

 

or

 

$cash = 1000;
$max = market_max($cash);
print_r($max);
